A very exciting new feature for Umajin is editing and integrated debugging for your JS components, actions and feeds. We are using the excellent new lightweight Microsoft Visual Studio Code.
This debugger lets a developer stop the program wherever they want using a breakpoint. They can then step through the code a line at a time.
While they are looking at the code they can also see all of the values to better understand what the code is doing.
This is a very powerful feature for developers who are creating new interactions and connectors for you to use in your projects.
